Embodiment 1

[0039] This embodiment provides a method for adjusting the inclination of a rolling mill, figure 1 It is a schematic flow chart of the method for adjusting the inclination of the rolling mill, and the method for adjusting the inclination of the rolling mill includes:

[0040] Step S1 , when the rolling mill is in a stable working state, detecting the tension on the working side of the rolling mill, the rolling force on the working side of the rolling mill, the tension on the driving side of the rolling mill, and the rolling force on the driving side of the rolling mill.

[0041] When the rolling mill is in an unstable working state, for example, during the starting process of the rolling mill, due to the influence of different working conditions, the tension on the working side of the rolling mill, the rolling force on the working side of the rolling mill, the driving force of the rolling mill The tension on the side and the rolling force on the driving side of the rolling mil...

Embodiment 2

[0054] This embodiment provides an inclination adjustment device for a rolling mill, figure 2 It is a structural schematic diagram of the inclination adjustment device of the rolling mill, and the inclination adjustment device of the rolling mill includes a tension detection element 11 , a rolling force detection element 12 , a controller 13 and an actuator 14 .

[0055] The tension detection element 11 is used to detect the tension on the working side of the rolling mill and the tension on the driving side of the rolling mill when the rolling mill is in a stable working state.

Abstract

The invention discloses an inclination adjusting method and device of a rolling mill. The method includes the steps that when the rolling mill is in a stable work state, the tensile force of the workside of the rolling mill, the rolling force of the work side of the rolling mill, the tensile force of the driving side of the rolling mill and the rolling force of the driving side of the rolling mill are detected; a tensile force deviation and a rolling force deviation are obtained; when the tensile force deviation meets the preset condition and an absolute value of the rolling force deviation is larger than a first preset rolling force, an inclination control signal is generated; according to the inclination control signal, the inclination direction of the rolling mill is adjusted to reducethe tensile force deviation; and when an absolute value of the tensile force deviation is smaller than a second preset tensile force and the absolute value of the rolling force deviation is smaller than a second preset rolling force, generating of the inclination control signal stops. The inclination adjusting method and device of the rolling mill prevent that due to the fact that the tensile force deviation is too large, the conditions of single-edge waves, deflection and even belt breaking occur to belt steel.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a method and device for adjusting the inclination of a rolling mill. Background technique [0002] Rolling is a pressure processing method in which the metal blank passes through the gap between a pair of rotating rolls, and the cross-section of the material is reduced and the length is increased due to the compression forming rolling of the rolls. This is the most commonly used production method for the production of steel products. It is mainly used to produce profiles, plates, and pipes. It is divided into two types: hot rolling and cold rolling. [0003] Hot rolling can destroy the casting structure of the steel ingot, refine the grains of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. Cold rolling is to use hot-rolled steel coils as raw materials, and then carry out...
